What's the Least Common Multiple (LCM) of 20 and 230?

Answer

LCM of 20 and 230 is
460

First common multiples: 460; 920; 1,380; …

460 is divisible by both: 460 ÷ 20 = 23, 460 ÷ 230 = 2 — and 23 and 2 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/20 by 23 and of y/230 by 2.

20 = 22 × 5

230 = 2 × 5 × 23
